Shower head having a water purifying function

Abstract

A shower device having a water purifying function includes a cartridge type filter formed with a water inlet at one end and a water outlet at the other end and means for showering such as a shower head connected to the water outlet of the cartridge type filter. The cartridge type filter contains a tannin layer consisting of a material comprising tannin, a bakuhanseki layer consisting of granular bakuhanseki formed in a layer, a ceramic layer consisting of granular ceramic formed in a layer, a magnetite layer consisting of broken pieces of magnetite formed in a layer and provided at least on the water inlet side or on the water outlet side of the ceramic layer, and magnetizing means such as magnets for magnetizing the magnetite layer.

What is claimed is: 
     
       1. A shower device having a water purifying function comprising a cartridge type filter formed with a water inlet at one end and a water outlet at the other end and means for showering connected to the water outlet of said cartridge type filter, said cartridge type filter containing a tannin layer consisting of a material comprising tannin, a bakuhanseki layer consisting of granular bakuhanseki formed in a layer, a ceramic layer consisting of granular ceramic formed in a layer, a magnetite layer consisting of broken pieces of magnetite formed in a layer and provided at least on the water inlet side or on the water outlet side of the ceramic layer, and magnetizing means for magnetizing said magnetite layer. 
     
     
       2. A shower device as defined in claim 1 wherein said magnetizing means comprises a pair of annular magnets provided both on the water inlet side and on the water outlet side of the ceramic layer in such a manner that these annular magnets coincide with each other in the direction of magnetic lines of force and that the direction of the magnetic lines of force is parallel to the direction of flow of water.
